I suppose it is not possible to import date repeat Rules with node import?
Whet I choose a node type with a date field with repeat options, this field shows up... but it is not possible to import the Rule (RRULE:FREQ=WEEKLY;INTERVAL=1;UNTIL=20100419T220000Z;WKST=SU)
I get an error "Fatal error: Cannot unset string offsets in /var/www/mng_6/sites/all/modules/date/date_repeat/date_repeat_form.inc on line 212" when trying.

Would it be difficult to implement this?
